To all whom it may concern:

Be it known that I, HARRY E. GAMPBEIL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Apparatus for Closing Window-Sashes, of which the following is a specification.

turned upward to form flanges J inclined toward one another. When the sash G is in raised position, an vupwardly projecting plate K on the front member L of the sash frame enters between the flanges J, as Shown in Fig. 4. he rear member M of said sash frame, which is united to said front member by welding or other suitable The 1nvention 18 an apparatus for closing means, has a rearwardly projecting ledge N. a window sash, or sashes, upon the attain- At each end of the lintel is a compartment ment of a predetermined degree of temperaformed by the two parallel transverse partiture of the surrounding atmosphere, and and the partition Q formed by for retaining said sash, or sashes, in closed bendmgthe partition P at right angles. As position. As is well known, it is frequently the partitions 0, P, which extend from the desirable, i eve t of a fir o curri g in rear vert 1cal wall of the llntel, do not reach n apartment or b ildi g, 1; close th wi across said lintel, a space R therein remains dows in order to cut oil access of air to the 1 Q 9 the p l n Q- fire, and this, after the fire has started, it the P Q P 0f each is often difficult or impossible to do.

A second collar I C, D, through which slots 12, also fast on shaft 5, has a latch arm laterally projecting fro the 13, curved over at its extremity 14E. Said sashes RG. Similar arm passes through openings in the lintel plates on the opposite side rails enter simibottom and plate H. ere is an elonlar slots in the opposite jamb. Between said gated opening 15 in collar 12 adapted to lintel and the upper ends of the jambs are receivea wedge 16, which may be loosened plates H and l having their facing edges c to Fig.

pass plates E to adjust the collar upon the shaft and after- 110 v ward tightened to retain said collar in adjusted position. A,bracket 17 on the under side of plate H carries one end of a fusible or destructible member 18, preferably of metalor alloy, the other end of said member engaging the extremity lei of latch arm 13. I may make this member of two pieces united together, as shown in Fig. 3, or of a single piece. Any material may be chosen for the destructible member which will become fused -or ruptured when the temperature surroundingthe same reaches a predatermined point, under which condition 1t 1s desired the sashes shall be closed and locked. On the under edge of latch arm 13 is a notch 19 which, when the up or sash is in the raised position shown in ig. 4, engages the ledge ll on said sash.

The operation of my ably placed at such an angle to one another that when the latch arm 13 engages the .estrnctible member 18, the arm '2'. is horizontal, as shown in Fig. 3. The hooked end 10 of the weight rod 9 then extends over.

said arm 7, so that the weight 8 is suspend ed by said rod 9, and the shaft 5 is prevented from rotating by the engagement of'arm' 13with said destructible member 18. 'Saidmember is, therefore, under.the strain of the weight 8. The sashes may now be both open, as shown in Fig. 3.

When the predetermined temperature is reached at which it is desired the sashes shall automatically close, the member 18 becomes ruptured. The arm 13 being released, the shaft 5 is free to be turned by descent of weight 8. As the weight falls, {the book. 10 disengaging from the arm 7), the projection 11 on said weight forces down the lower sash, and through the connecting.

suspension chains '1 the upper sash iscorrespoi'idingly raised and closed, as shown in Fig; l. lVhen the upper sash reaches its desired closed position, the ledge N thereon is in position to be and is engaged by the notchsaid. sash into closed position, a latch for preventing the operation of said moving means, and'means controlled by and open ating upon. a predetermined rise in. temperature for releasing said latch.

2. A window-frame, a movable sash device is as follows Thearms 7 and 13 on shaft.5 are prefertherein, means normally operating to move said sash into closed position, a latch for preventing the operation of said moving means and constructed to engage said sash, meai'is-controlled by and operating upon a predetermined rise intemperature for releasing said latch, and means for moving said released latdh into engagement with said closed sash.'

3. A window-frame, a vertically movable sash therein, a weight connected to said sash and operating by gravity to move said sash into closed position, a latch for holding said weight raised, and means controlled by and operating upon a predetermined rise of temperature to. release said latch and permit the descent of said weight.

I 4. A window-frame,two vertically movable mutually counterbalanced sashes therein, suspension means for said sashes,a shaft journaled in said frame above said sashes, an arm on said shaft, a weight suspended on said arm and extending over the top rail of the lower sash, a latch arm on said shaft, and a member of material destructible at a predetermined temperature connected at its ends respectively to' a fixed support and to said latch arm; whereby said weight is held in raised position until on the attainment of said predetermined temperature, said destructible member is destroyed, thereby. releasing said latch arm and permitting said weight to move downwardly said lower sash,

and through said suspension means to close said upper sash.

5; A window-frame, a vertically movable sash therein, a shaft journaled in said frame above said sash, a weight connected to said sash and normally operating by gravity to move said sash into closed position; an. arm on said shaft, a vertical rod on said weight booked at its upper end to engage said arm and suspension weight, a latch arm on said shaft, and a member of material. destructiblc at a predetermined temperature connected to said frame and said latch arm; whereby said weight is held in raised. position until on the attainment of said predetermined temperature, said destructible member is ruptured, thereby releasing said latch arm and permitting said weight to fall and gloss said sash.

6. A window-frame, comprising hollow jambs having vertical slots in their inner walls, and a box lintel, two mutually counterbalancing sashes slidable in said slots, suspension pulleys inclosed in said lintel, suspension chains Within said ja-Inbs passing over said pulleys and connected at their ends .to said sashes, a shaft in said lintel, an. arm

on said shaft, a weight in one of said jambs disposed above the lower sash and suspended from saidjarm, a latch arm on said shaft, and a member of material destructible at and by a predetermined rise in temperature connected. at one end to said frame and at its other end engaging said latch arm; whereby upon the attainment of said predetermined ten'1 erature said member shall be ruptured thereby freeing said latch arm and said weight, and whereby said Weight in falling causes the closing of both of said sashes.

7. A window-frame, a vertically slidable sash in said frame, a suspension device, and a counterweight for'said sash, a second weight disposed above said counter-Weight, releasable means for suspending said lastnamed weight, and means operating upon and controlled by a predetermined rise in temperature for releasing said second Weight to over-balance said sash and move the same into closed position.

8. A window-frame, a sash vertically slidable therein, a suspension device, means for couliter-balancing said sash, and means operating upon and controlled by a predetermined rise in temperature for overbalancing said sash and thereby moving the same into closed position.
